BACKGROUND OF THE PRESENT INVENTION Field of Invention

The present invention relates to a foldable appliance, and moreparticularly to a foldable container with foldable supporting frame andfolding method thereof.

Description of Related Arts

Many foldable brackets are designed and aid for daily entertainmentactivities. Accordingly, a height of the bracket can be raised to liftup the appliance from the ground during the use of the appliance. As aresult, the user does not have to bend or squat to use the appliance.Once the bracket is folded, a size of the bracket is reduced for storageand space saving.

Household temporary container, especially large size receptacle, ispopular to be used as basin, bathtub or swimming pool for bathing,cleaning or playing purpose. This temporary container is convenient formost families. For example, the user is able to move this temporarycontainer from place to place, such as bathroom or yard, as needed.Since this kind of container needs to have space large enough to hold atleast a child or pet inside while having enough space to contain wateror cleaning liquid, the conventional container is generally made inlarger size. This kind of rigid container is convenient for mostfamilies also take wider space for using water, usually in outdoor areaor bathroom. It is known that such relatively large container is notrequired to be used all the time or even daily use, this temporarycontainer will not be the primary consideration for most families inview of storage, especially for urban families. Since the storage inurban family is very limited, it is a problem to store the temporarycontainer when it is not in used. These defects of the temporarycontainer cannot be solved and this temporary container is not practicalin use.

Specifically, in order to reduce the space occupied by the temporarycontainer when it is not in use, the current temporary container isdesigned to be inflatable, such that the temporary container is reusedby inflating and deflating the temporary container. Usually, thetemporary container is inflated by an inflator or inflatable pump.Before using the inflatable temporary container, it is necessary toinitially place the inflatable temporary container in a preset position,and then use the inflatable pump to inflate the inflatable temporarycontainer for at least five minutes for fully inflate the temporarycontainer by filling a predetermined amount of gas to bias against theinner sidewall of the temporary container so as to support the shape ofthe temporary container. In other words, it is very troublesome to setupthe temporary container. If the inflatable pump is damaged or lost, theinflatable temporary container cannot be used at all. Moreover, in orderto facilitate the temporary container being folded after deflation, itis also necessary to provide an air exhaust vent at the temporarycontainer. If the air exhaust vent is poorly sealed, air leakage islikely to occur. Once the inflatable temporary container has an airleakage problem, it is easy to cause the water or cleaning liquidcontained in the temporary container to leak out, especially for thetemporary container used in the living room. In other words, if thewater or cleaning fluid leaks out of the temporary container, it willinevitably cause water damage to the home environment. Furthermore,during the manufacturing process of the inflatable temporary container,the air exhaust vent is affixed to the sidewall of the temporarycontainer to communicate with an interior air chamber of the inflatabletemporary container. It is difficult to ensure the tightness between thesidewall and the air exhaust vent.

For the temporary container made of plastic, it must be stored indoorsin order to prevent the plastic aging from directly exposing under thesun. Therefore, it is necessary to save a larger space for storing thetemporary container. In some cases, the entire temporary container isused to store various items inside the container during storage, suchthat these items must be placed somewhere in the storage room. However,before the next use of the temporary container, additional steps arerequired to take out the items and clean the container before use.

In addition to liquid containers, some cooking utensils, such as grills,table tops, etc., have similar problems. One of the major problems isstability after it is setup. Since the foldable bracket is movable, itis a major concern how to keep the stability of the foldable bracketwhen it is unfolded. The existing foldable bracket is basicallyconstructed to have a X-shaped pivotal structure. This structureprovides high mobility and is easy to deform during use. The foldableangle may increase permanently as the structure is frequently used.

In addition, the temporary container is directly placed on the groundwhen it is used, wherein the user will need to bend over when helpingchildren or pets to clean, which is likely to hurt health the user,especially the back of the user.

Even though the existing foldable brackets can be folded, the foldingoperation thereof requires many steps. Basically, it requires two handsto close the bracket, and may also need to rotate and fold differentparts of the bracket frame. So, the traditional folding process of thefoldable bracket is very troublesome. Since the folding process iscomplicated and difficult, the user will merely keep the temporarycontainer being unfolded all the time, which fails to achieve the mainpurpose of folding up the temporary container for storage to save thespace.

Referring to FIGS. 1 to 13 of the drawings, a foldable containeraccording to a preferred embodiment of the present invention isillustrated, wherein the foldable container is suitable for containingwater or liquid for cleaning therein to serve as a bathtub or a swimmingpool. The foldable container comprises a foldable supporting frame 10,an operation switch 20 being operated through a pulling operation by apulling force to operate and move the foldable supporting frame 10between an unfolded mode and a folded mode, and a container body 30being placed and supported on the foldable supporting frame 10. In otherwords, when the foldable supporting frame 10 is unfolded, the containerbody 30 is also unfolded for containing the liquid therein. When thefoldable supporting frame 10 is moved to its folded mode, the containerbody 30 and the foldable supporting frame 10 are folded together, suchthat the entire foldable container can be stored in a folded state.

Preferably, when the foldable supporting frame 10 is unfolded, thecontainer body 30 is automatically unfolded along with the foldingoperation of the foldable supporting frame 10. In other words, duringthe folding process of the foldable supporting frame 10, the containerbody 30 is automatically folded when the foldable supporting frame 10 isfolded.

It is worth mentioning that the present invention provides a singlepulling operation referring to the one-way mode when the foldablecontainer is operated to moved and converted from the unfolded mode tothe folded mode. In other words, operating the foldable container at thesame direction can move the foldable container from the unfolded mode tothe folded mode. Preferably, the single pulling operation in the presentinvention refers to the one-way pulling operation when operating thefoldable container to move from the unfolded mode to the folded mode. Inother words, pulling the foldable container at the same direction at onetime can move the foldable container from the unfolded mode to thefolded mode. It is appreciated that those skilled in the art shouldunderstand that pulling the foldable container at the same direction indifferent stages can also move the foldable container from the unfoldedmode to the folded mode. For example, pulling the foldable containertwice toward the same direction can also move the foldable containerfrom the unfolded mode to the folded mode. As shown in FIGS. 1 and 2 ,the container body 30 according to the preferred embodiment is fixedlycoupled at the foldable supporting frame 10. The container body 30 isdriven by the foldable supporting frame 10 to be folded and unfolded.When the container body 30 is needed to be unfolded, the foldablesupporting frame 10 is operated to unfold the container body 30. It isworth mentioning that the foldable container can be unfolded as a wholesystem without any additional step. No additional step is required toopen up the container body 30 or improve the stability of the containerbody 30. When the foldable supporting frame 10 is operated to expand andunfolded, the container body 30 is simultaneously expanded at its setupstate. In addition, folding up the container body 30 by folding thefoldable supporting frame 10 is similar. When the foldable supportingframe 10 is folded, the foldable supporting frame 10 will drive thecontainer body 30 to fold. Therefore, the folding or unfolding of thefoldable container can be easily operated.

As shown in FIG. 3A, the foldable supporting frame 10 comprises at leasttwo top supporting arms 11, at least two folding arms 12, and at leastfour supporting legs 13. Each of the top supporting arms 11 is placed onthe folding arm 12 and the supporting leg 13, wherein the folding arm 12and the top supporting arm 11 are supported by the supporting leg 13.Preferably, the number of the top supporting arms 11, the folding arms12 and the supporting legs 13 are corresponding, wherein each of the topsupporting arm 11 and each of the folding arms 12 are correspondinglysupported by the supporting leg 13.

It is worth mentioning that the folding arms 12 are pivotally connectedto each other by the operation switch 20. The rotation of the foldingarm 12 is configured to drive the folding or unfolding movement of thetop supporting arm 11 and the supporting leg 13. When the foldablesupporting frame 10 is in the folded mode, the two folding arms 12 arearranged to be folded and overlapped each other. When the foldablesupporting frame 10 is in the unfolded mode, the two folding arms 12 arearranged to be unfolded to open and extended flatly. Therefore, when thefolding arm 12 is folded, the top supporting arm 11 and the supportingleg 13 are folded following the folding operation of the folding arm 12.Therefore, by only folding the folding arm 12, the entire foldablesupporting frame 10 is folded, which is convenient in operation. Whenthe foldable supporting frame 10 is folded, the container body 30 iscorrespondingly folded.

As shown in FIG. 3A, the operation switch 20 is connected to two ends ofthe two folding arms 12 to control the foldable supporting frame 10 toswitch between folding and unfolding. The switch 20 can be furtheroperated by being pulled to move the folding arm 12 from the unfoldedmode to the folded mode. In other words, when the foldable supportingframe 10 is in the unfolded mode, the operation switch 20 is pulled todrive and move the folding arm 12. In other words, the folding arm 12 isfolded due to gravity and loss of supportability. Though the pullingoperation, the operation switch 20 is pulled to fold the foldablesupporting frame 10.

Specifically, the two folding arms 12 are pivotally connected with eachother around a rotating rod 121, wherein the rotating rod 121 is placedbetween the ends of the two folding arms 12. The rotating rod 121 isinstalled into the operation switch 20. The two folding arms 12 arerotated around the operation switch 20, wherein the operation switch 20is configured to restrict the rotations of the folding arms 12 relativeto each other. According to the first embodiment, one of the foldingarms 12 is fixed to the operation switch 20, while another folding arm12 is relatively free to rotate relative to the operation switch 20. Inother words, one of the folding arms 12 is defined as a fixed foldingarm 1202, and another folding arm 12 is a free rotatable folding arm1201. The fixed folding arm 1202 is installed into the operation switch20 together with the rotating rod 121. The free rotatable folding arm1201 is rotatably coupled at the operation switch 20 around the rotatingrod 121.

In addition, the rotation of the fixed folding arm 1202 and the freerotatable folding arm 1201 around the rotating rod 121 are asymmetrical.In other words, when the fixed folding arm 1202 and the free rotatablefolding arm 1201 are folded with each other, the fixed folding arm 1202and the free rotatable folding arm 1201 are staggered and stacked witheach other and will not contact or collide with each other. On one side,the fixed folding arm 1202 and the free rotatable folding arm 1201 willnot be mechanically damaged during the folding and unfolding operations.On the other side, after folding, a retention channel is formed betweenthe fixed folding arm 1202 and the free rotatable folding arm 1201.

It is worth mentioning that the end of the free rotatable folding arm1201 is further transversely connected to a switch rod 122. When thefolding arm 12 is flatly unfolded, the switch rod 122 is firmlysupported by the operation switch 20, wherein the free rotatable foldingarm 1201 is parallel to the fixed folding arm 1202. When the switch rod122 is supported, the free rotatable folding arm 1201 is relativelysupported on the same side of the fixed folding arm 1202. When theoperation switch 20 is configured to keep supporting the switch rod 122,the free rotatable folding arm 1201 is configured to remains relativeparallel to the fixed folding arm 1202. When the switch rod 122 isreleased from the operation switch 20, the free rotatable folding arm1201 will lose its support. Under the action of gravity force, the freerotatable folding arm 1201 will rotate around the rotating rod 121 andfold toward the fixed folding arm 1202. In other words, when the switchrod 122 is supported by the operation switch 20, due to the restrictionof the operation switch 20, the folding arm 12 is unfolded and isdifficult to change its position. Once the switch rod 122 is detachedfrom the operation switch 20, the folding arm 12 can rotate around therotating rod 121 to be folded. Therefore, the folding arm 12 iscontrolled by the operation switch 20 for controlling the movement ofthe folding arm 12, wherein the folding position or the unfoldingposition of the foldable supporting frame 10 is indirectly controlled bythe operation switch 20.

In addition, the supporting legs 13 and the folding arms 12 arepivotally connected to pivot shafts 130 respectively. When the foldingarm 12 is operated to rotate around the rotating rod 121, the angle anddistance between the folding arms 12 are changed while the supportingleg 13 is driven to rotate around the pivot shafts 130. Each of thesupporting legs 13, each of the folding arms 12, and the pivot shaft 130are formed into a rotatable X-shaped frame. Since the movements of thefolding arms 12 are transmitted to the supporting legs 13, thesupporting legs 13 are automatically moved for being further folded orunfolded via the folding arms 12.

Furthermore, as shown in FIG. 3B, the container body 30 is detachablyconnected to the foldable supporting frame 10. The container body 30 canbe further removed from the folding supporting frame 10 for being andcleaned or disinfected.

Furthermore, the top supporting arm 11 is driven to rotate by thesupporting leg 13 via a folding assembly 110, wherein the foldingassembly 110 is installed at the top of the supporting leg 13. When thesupporting leg 13 is folded or unfolded as the folding arm 12 rotates,the top supporting arm 11 is driven to rotate around the foldingassembly 110. Each of the supporting legs 13, each of the top supportingarms 11, and the folding assembly 110 are formed into a rotatableinversed V-shaped frame. Since the folding assembly 110 is driven, it isnot necessary to fold or unfold the supporting leg 13 because themovement of the folding assembly 110 will be transmitted to thesupporting leg 13.

In detail, the folding assembly 110 comprises a rotatable base 111 and alinkage unit 112. The rotatable base 111 is coupled at the end of thetop supporting arm 11 to receive the upper end of the supporting leg 13in the rotatable base 111. The linkage unit 12 comprises two linkagemembers 1121 respectively mounted on the top end of the supporting leg13 and the end of the top supporting arm 11. The linkage members 1121are connected by link shafts 1122, so that the angle between each topsupporting arm 11 and each supporting leg 13 can be controlled and has amaximum angle limitation. Each of the top supporting arms 11, each ofthe supporting legs 13 and the linkage member 1121 are formed in an Ashape, wherein the top supporting arms 11 will drive the supporting legs13 to move, while the supporting legs 13 will drive the top supportingarm 11 to move around the rotatable base 111.

Preferably, by operating the operation switch 20 to release the switchrod 122 and to fold the folding arm 12, the supporting leg 13 and thetop supporting arm 11 are corresponding folded. Preferably, the topsupporting arm 11 is expanded to further drive the folding arm 12 to besupported on the operation switch 20 and to drive the supporting leg 13to expand.

Furthermore, each of the supporting legs 13 is configured forcorrespondingly installing an extension leg 14 for increasing the heightof the top supporting arm 11 and keeping the container body 30 on thetop supporting arm 11 in a preset position, as shown in FIG. 5 . Throughthe extension legs 14, the container body 30 is supported and raisedabove the ground for hygienic and cleaning purpose while the water orcleaning liquid is contained in the container body 30. As a result, theuser can comfortably use the container body 30 without bending theuser's body.

The container body 30 comprises a surrounding wall 31 and a bottom wall32 sealingly connected to the surrounding wall 31 to form the containerbody 30 having a bowl shape and a surrounding edge 310 defining anopening thereof surrounded by the edge 310. The edge 310 of thesurrounding wall 31 is disposed on the top supporting arm 11 of thefoldable supporting frame 10. In one alternative mode of the presentinvention, the container body 30 is detachably mounted on the topsupporting arm 11 for replacement. The container body 30 furthercomprises at least one pocket 33 placed on the surrounding wall 31. Thepocket 33 is configured for keeping other items therein to facilitatethe reaching of items when using liquid for cleaning or playing in thecontainer body 30.

Preferably, as shown in FIG. 3B, the edge 310 of the surrounding wall 31is constructed to have a fixing rib 312 and an edge sleeve 311, whereinthe fixing rib 312 is configured to pass through the edge sleeve 311,such that the edge 310 is supported with its shape. The top supportingarm 11 further comprises a rod body 101, wherein the rod body 101 has afixing cavity 102 formed on one side of the rod body 101. The fixingcavity 102 is extended through the rod body 101, wherein the edge 310 ofthe surrounding wall 31 is installed inside the fixing cavity 102.

Specifically, the fixing rib 312 is extended into the fixing cavity 102of the rod body 101, such that the edge sleeve 311 to be carried issuspended and fixed to the rod body 101. In the first embodiment, thefixing cavity 102 of the rod body 101 has a U-shaped configuration,wherein the fixing rib 312 is configured to enter from an opening of thefixing cavity 102 into the fixing cavity 102. Furthermore, the edgesleeve 311 is formed in a U-shape and is also connected to the rod body101 of the top supporting arm 11 in a U-shape. When the surrounding wall31 is needed to be disassembled, the fixing rib 312 relatively removedfrom the fixing cavity 102 of the rod body 101, wherein the fixing rib312 is completely removed from the top supporting arm 11. Preferably,the rod body 101 is pulled to release the supportability of the edgesleeve 311. More preferably, the fixing rib 312 is detachably connectedto the sleeve edge 311, such that the sleeve edge 311 can be furtherfolded or cleaned.

It is worth mentioning that the bottom wall 32 has a drain port 322 fordraining the water or cleaning liquid in the container body 30.Preferably, the drain port 322 is set at the lowest location or area ofthe bottom wall 32 for effectively draining the liquid in the containerbody 30. The drain port 322 is able to connect a drain pipe 40 to allowliquid to flow out of the container body 30 along the drain pipe 40. Adrain plug can be detachably plugged at the drain port 322 to preventthe liquid being drained out the container body 30 through the drainport 322.

Particularly, as shown in FIGS. 2 and 7C, when the foldable supportingframe 10 is in the folded mode, the drain pipe 40 is located in theretention channel. The retention channel is formed with a predeterminedwidth because of the asymmetric folding of the fixed folding arm 1202and the free rotatable folding arm 1201. The drain pipe 40 is located inthe retention channel and will not be pressed by the fixed folding arm1202 and the free rotatable folding arm 1201. In other words, the drainpipe 40 is held in the retention channel at the folded mode, wherein thedrain pipe 40 is enclosed between two sides of the fixed folding arm1202 and the free rotatable folding arm 1201. Therefore, the drain pipe40 will not be damaged by any external impact, and the drain pipe 40 iskept in a certain position to avoid any unwanted movement, vibration orswinging.

The bottom wall 32 further comprises a handle 321 connected to theoperation switch 20. The operation switch 20 can be operated byoperating the handle 321 to fold the folding arm 12.

As shown in FIG. 4 , the operation switch 20 comprises a main body 21, aslider 22 movably coupled at the main body 21, and a resilient member 23connecting the main body 21 to the slider 22 so as to fasten the slider22 in the main body 21. The main constructed to have a shape for beingheld on the end of one of the folding arms 12. Particularly, the mainbody 21 is rotatably coupled at the free folding arm 1201 and fixedlycoupled at the fixed rotatable folding arm 1202. It is worth mentioningthat the slider 22 is partially protruded out of the main body 21 due tothe elastic force of the resilient member 23. When the resilient member23 is configured to push the slider 22 protruding out of the main body21, the slider 23 can support the folding arm 12 in place. Once theslider 22 is configured to move inside the main body 21, the folding arm12 will lose support, such that the folding arm 12 will fall down androtate around the rotating rod 121. When the folding arm 12 is no longersupported by the slider 22 of the operation switch 20, the folding arm12 is folded. As a result, the two folding arms 12 are folded to overlapeach other.

When the free rotatable folding arm 1201 is rotated, is supported by theslider 22, and is parallel to the fixed folding arm 1202, the foldingarm 12 is unfolded flatly, while the folding supporting frame 10 is inthe unfolded mode. When the slider 22 is configured to move back in themain body 21, the free rotatable folding arm 1201 is configured to dropand overlappedly fold with the fixed folding arm 1202.

According to the preferred embodiment, the main body 21 is formed withtwo fixed arm cavities 211, two free arm cavities 212 and a slidercavity 213. The end of the fixed folding arm 1202 is fixedly coupled inthe fixed arm cavity 211, and the rotating rod 121 is configured to passthrough the fixed arm cavity 211. The end of the free rotatable foldingarm 1201 is movably arranged in the free arm cavity 212 and rotatablyconnected around the rotating rod 121. Therefore, the rotating rod 121is configured to pass through the fixed arm cavity 211 and the free armcavity 212. In other words, both ends of the free rotatable folding arm1201 and both ends of the fixed folding arm 1202 surround the rotatingrod 121. The fixed folding arm 1202 and the fixed arm cavity 211 of themain body 21 remain stationary, wherein the free rotatable folding arm1201 is configured to rotate in the free arm cavity 212 of the main body21. The slider 22 is movably disposed in the slider cavity 213 to bemoved in or pushed by the resilient member 23 to move out of the slidercavity 213.

The switch rod 122 is located outside of the main body 21 and isconfigured to apply a pushing force to the slider 22 to move the slider22 backward in the slider cavity 213. When the switch rod 122 is liftedto force the slider 22 to move in, and when the free rotatable foldingarm 1201 is rotated around the rotating rod 121 to expand, the slider 22is pushed to move back into the slider cavity 213. When the switch rod122 passes over the slider 22 that no force is applied to the slider 22,the slider 22 is pushed out of the slider cavity 213 by the resilientmember 213 to protrude out of the slider cavity 213 again. The switchrod 122 is then supported by the slider 22 when protrude out of theslider cavity 213. Under this circumstances, the switch rod 122 cannotpush the slider 22 back, and the slider 22 bears the weight of theswitch rod 122. When the slider 22 is kept protruding out of the slidercavity 213 and the switch rod 122 is still supported by the slider 22 ofthe operation switch 20, the free rotatable folding arm 1201 and thefixed folding arm 1202 are relatively unfolded, while the folding arm 12is laid flat and stable.

The slider 22 has a supporting end 221 defining a unidirectionalinclined sloping surface. The switch rod 122 is configured to push thesupporting end 221 along the sloping surface thereof. The supporting end221 of the slider 22 is configured to support the switch rod 122 on theplanar surface thereof to bear the weight of the switch rod 122 so as toprevent the switch rod 122 being pushed back.

The slider 22 has a pulling end 222 firmly connected to a pulling strap24. By pulling out the pulling strap 24, the slider 22 is configured toresist the elastic force of the resilient member 23 and to move backwardin the slider cavity 213.

The slider 22 further comprises a stopper 223 protruded from the mainbody 21 to engage with the slider 22 inside the slider cavity 213 forpreventing the slider 22 from moving out of the slider cavity 213 viathe pushing force of the resilient member 23. In other words, the slider22 is pushed by the resilient member 23 and is held by the stopper 223in order to be held in the slider cavity 213. Also, the slider 22 isrestricted to move along a specific path in the slider cavity 213.According to the preferred embodiment, the slider 22 further comprisesat least one slide rail 2134 formed inside the slider cavity 213 tolimit the moving direction and distance of the slider 22. The slider 22further comprises at least one sliding leg 224, wherein the sliding leg224 is correspondingly engaged with the sliding rail 2134 of the slidingblock cavity 213.

The slider cavity 213 has a supporting opening 2131 corresponding to thefree rotatable folding arm 1201 and a pulling opening 2132 correspondingto the fixed folding arm 1202. The slider 22 is pushed by the resilientmember 23 to protrude out from the supporting opening 2131, wherein whenthe slider 22 is pressed by the switch rod 122, the slider 22 is pulledback toward the pulling opening 2132. The slider cavity 213 further hasa limitation window 2133. The limitation window 2133 is preferablylocated at the top of the main body 21. The limitation window 2133 isconfigured to accommodate the stopper 223 of the slider 22 inside thelimitation window 2133. The limitation window 2133 is configured toblock the stopper 223 and move within the area of the limitation window2133. In other alternative modes, the limitation window 2133 can beshaped as a groove to limit the movement of the stopper 223.

The pulling strap 24 is extended out of the main body 21 through thepulling opening 2132 from the pulling end 222 of the sliding block 22.When the pulling strap 24 is actuated to pull the slider 22 back to theslider cavity 213, the supporting end 221 is moved backward, such thatthe support of the switch rod 122 is dismissed due to the backwardmovement of the supporting end 221. The stopper 223 is restricted tocontinuously move backward by the limitation window 2133, so as to avoidfurther movement of the slider 22.

The pulling strap 24 has one end connecting to the handle 321 at thebottom wall 21 of the container body 30 and an opposed end connecting tothe slider 22. Therefore, when the handle 321 is pulled to lift thecontainer body 30, the pulling strap 24 is configured to transmit thepulling force to pull the slider 22 to move the slider 22 into theslider cavity 213. Only one action of pulling the handle 321 of thecontainer body 30 is required for operating the operation switch to foldthe foldable supporting frame 10.

In addition, the relationship and movement of the foldable containerduring the unfolding process according to the preferred embodiment areshown in FIGS. 6A to 6C.

When the foldable container is actuated for being used, as an example,the top supporting arms 11 are opened from the folded mode. The topsupporting arms 11 are configured to drive the supporting legs 13 tomove and expand around the folding assembly 110. The supporting legs 13are configured to drive the folding arms 12 to open about the pivotshafts 130. In other words, the folding arms 12 are driven to rotateabout the pivot shafts 130 by the movements of the supporting legs 13.When the folding arms 12 are unfolded to lay flat on each other, thefolding arms 12 are rotated about the rotating rod 121. The folding arm12 will be supported by the operation switch 20 to restrict its furthermovement.

Specifically, when the free rotatable folding arm 1201 is rotated to thefixed folding arm 1202, the free rotatable folding arm 1201 is rotatedto be supported by the slider 22 of the operation switch 20 and isparallel to the fixed folding arm 1202, such that the folding arms 12are expand to lay flat on each other. The foldable support frame 10 isin the unfolded mode. When the free rotatable folding arm 1201 is drivento rotate, the switch rod 122 is lifted to apply the force to thesupporting end 221 of the slider 22. Then the slider 22 is pushed tomove back into the slider cavity 213. After the switch rod 122 iscontinuously raised to pass over the slider 22, the slider 22 is notaffect by the force, such that the slider 22 is pushed out of the slidercavity 213 by the resilient member 23 to protrude out of the slidercavity 213. The switch rod 122 is supported on the slider 22 when theslider 22 is protruded out of the slider cavity 213. Under thiscircumstance, the switch rod 122 cannot push the slider 22 back byexerts its weight on the slider 22. Therefore, the folding arm 12 isunfolded and is stably supported by the switch 20. The foldable supportframe 10 is moved at its unfolded mode. The container body 30 is openedup as the top supporting arms 11 are expanded.

Accordingly, as the top supporting arm 11 of the foldable support frame10 is unfolded, the folding arm 12 is stably supported by the operationswitch 20. Furthermore, under the movement of the top supporting arm 11,the container body 30 is actuated to be opened.

In addition, the relationship and movement of the foldable containerduring the folding process according to the preferred embodiment areshown in FIGS. 7A to 7C.

In order to fold the foldable container, the handle 321 is pulled tolift the container body 30, such that the pulling strap 24 will transmita pulling force to pull the slider 22 to move back in the slider cavity213. When the folding arm 12 is unfolded, the supporting end 221 willsupport the switch rod 122 on its planar surface to bear the weight ofthe switch rod 122 without being pushed back. When the slider 22 ismoved backward in the slider cavity 213, the slider 22 will resist theelastic force of the resilient member 23. The switch rod 122 of thefolding arm 12 will be dropped after losing the supportability so as tocause the free rotatable folding arm 1201 to rotate about the rotatingrod 121. In other words, the free rotatable folding arm 1201 is droppedand folded with the fixed folding arm 1202.

When two arm portions of the folding arm 12 are folded with each other,the top supporting arms 11 and the supporting legs 13 are also foldedaccordingly. The rotation of the folding arm 12 will drive thesupporting legs 13 to move about the pivot shafts 130. In other words,the supporting legs 13 are configured to rotate with the foldingmovements of the folding arms 12, such that the top supporting arm 11 isdriven to rotate around the folding assembly 110 to be folded.

Accordingly, when the pulling strap 24 is pulled to operate theoperation switch 20, the folding arm 12 will lose the support of theoperation switch 20. Then, when folding arm 12 is folded due to gravity,the supporting legs 13, the top supporting arms 11 and the containerbody 30 are also folded along with the folding movements of the foldingarms 12. Therefore, the foldable container is folded up by one singlepulling action.

As shown in FIGS. 8 to 10B, a foldable container according to a secondembodiment illustrates an alternative mode of the first embodiment,wherein the difference between the first and second embodiments is thatthe container body 30′ is detachably coupled on the foldable supportingframe 10′. It is worth mentioning that the container body 30′ can be anyconventional container suitable for being carried by the foldablesupporting frame 10′.

The foldable supporting frame 10′ comprises at least two folding arms12′ and at least four supporting legs 13′. Preferably, the number of thefolding arms 12′ and the number of the supporting legs 13′ are designedaccordingly. Each of the folding arms 12′ is correspondingly supportedby the two supporting legs 13′.

In addition, according to the embodiment, the supporting legs 13′ arepivotally connected to each other about the pivot shaft 130′ and aredriven by the folding arms 12 to rotate about the pivot shaft 130′. Asshown in FIGS. 9A and 9B, as the folding arms 12′ rotate about therotating rod 121′ to be folded or unfolded, the angle and distancebetween the folding arms 12′ will change. The supporting legs 13′ arealso driven to rotate about the pivot shaft 130′.

According to the second embodiment, two of the operation switches 20 areinstalled on one of the folding arms 12′. The operation switch 20 hasthe same structure and function as the above-mentioned first embodiment,and thus not be repeated here. However, the switch rod 122′ is designedand shaped differently. The switch rod 122′ is integrally formed on thefolding arm 12′ for providing supporting purpose.

In addition, FIGS. 9A to 9B illustrate the relationship and movement ofunfolding the foldable container according to the preferred embodiment.

The foldable supporting frame 10′ is opened from the folded mode. Thesupporting legs 13′ are driven by the folding arms 12′ and are expandedabout the pivot shafts 130′. The supporting legs 13′ can drive thefolding arms 12′ to be opened. When the folding arms 12′ are unfolded tolay flat with each other, the folding arms 12′ are rotated about therotating rod 121′. The folding arm 12′ will be supported by theoperation switch 20 to restrict further downward movement, and furtherupward movement is restricted by the supporting leg 13′ and the pivotshaft 130′.

Specifically, when one of the folding arms 12′ is rotated toward anotherfolding arm 12, the switch rod 122′ is lifted to the supporting end 211of the slider 22. Each of the sliders 22 is configured to support theside of the switch rod 122′, such that the switch rod 122′ issymmetrically supported by the two operation switches 20. Then, each ofthe sliders 22 is pushed by the switch rod 122′ to move into the slidercavity 213, such that the switch rod 122′ will continue to lift and passthe slider 22. Each of the sliders 22 is pushed out of the slider cavity213 by the resilient member 23 so as to protrude out of the slidercavity 213 again. The switch rod 122′ is supported by the slider 22 andplaced on the two operation switches 20 when the slider 22 is protrudedout of the slider cavity 213. Under the circumstance, the switch rod112′ cannot push the slider 22 backward, and the weight of the switchrod 122′ is supported on the slider 22. Then, the folding arm 12′ isunfolded and is stably supported by the operation switch 20. Thefoldable supporting frame 10′ is then moved at the unfolded mode. Thecontainer body 30′ can be placed on the folding arms 12′.

Accordingly, as the folding arm 12′ or the supporting leg 13′ of thefoldable supporting frame 10′ is unfolded, the folding arm 12′ is stablysupported by the operation switch 20, such that the switch lever 122′can support the weight of the container body 30′.

In addition, relationship and movement of the foldable container duringthe folding process according to the preferred embodiment are shown inFIGS. 10A to 10B.

When the folding arm 12′ is unfolded, the switch rod 122′ is supportedon the planar surface of the supporting end 221 to support the weight ofthe switch rod 122′ without being pushed back. In order to fold thefoldable container, it is necessary to pull the two pulling straps 24′,such that each slider 22 is moved backward in the slider cavity 213.Each of the sliders 22 is pulled back in the slider cavity 213 againstthe elastic force of the resilient member 23. The switch rod 122′ of thefolding arm 12′ will lose the support, and then will fall and rotateabout the rotating rod 121′. In other words, one of the folding arms 12′is dropped for being folded with another folding arm 12′. The rotationof the folding arm 12′ will drive the supporting leg 13′ to move aboutthe pivot shaft 130′. In other words, as the folding arm 12′ is folded,the supporting leg 13′ is rotated correspondingly.

Normally, when the pulling strap 24 is pulled to actuate the operationswitch 20, the folding arm 12′ will lose the support provided by theoperation switch 20. Then the folding arm 12′ is folded by its owngravity, wherein the supporting leg 13′ is folded as the folding arm 12′is folded. Therefore, the foldable container is folded by the singlepulling action.

In an alternative mode of the present invention, two pulling straps 24can be connected end-to-end. Then, by pulling only one of the pullingstraps 24, the two operation switches 20 can be operated. In addition,the two ends of the pulling strap 24 are securely fastened to the twosliders 22 respectively. By pulling the pulling strap 24, the twooperation switches 20 are operated at the same time.

Moreover, as shown in FIGS. 11 to 13 , a foldable container according toa third embodiment illustrates another alternative mode of the firstembodiment, wherein the difference between the first and thirdembodiment is that the third embodiment further comprises a mattress 50Adisposed in the container body 30, such that the container body 30serves as a bed or a resting basket.

In other words, at least two folding arms 12 and at least foursupporting legs 13 are correspondingly configured, wherein each of thefolding arms 12 is correspondingly supported by two supporting legs 13.Similarly, the supporting legs 13 are pivotally connected to each otherabout the pivot shaft 130, wherein the supporting leg 13 is driven bythe folding arm 12 to rotate about the pivot shaft 130. As the foldingarms 12 rotate about the rotating rod 121 to fold or unfold, the angleand distance between the folding arms 12 change. The supporting leg 13is also driven to rotate about the pivot shaft 130. The operation switch20 is coupled at one of the folding arms 12. The operation switch 20 hasthe same structure and function as the above mentioned first embodiment,and thus not being repeated here.

It is worth mentioning that the extension legs 14A of the foldablesupporting frame 10 are implemented differently in the third embodiment.The extension leg 14A further comprises a rocking frame 141A, two cornerframes 142A, and two foot stands 143A, wherein the rocking frame 141A isan elongated bar shape and is formed in a curved manner, wherein twoends of the rocking frame 141A is coupled to the two corner frames 142Arespectively, wherein the foot stands 143A are pivotally coupled at thecorner frames 142A respectively. The rocking frame 141A is arrangedextended along a lower part of the supporting leg 13 in a convex mannerfor supporting on the ground. Each of the foot stands 143A comprises asupporting stand 1431A and a swinging stand 1432A integrally extendedtherefrom. For retaining the extension leg 14A at a stationary position,the supporting stands 1431A are rotatably extended toward a direction ofthe supporting leg 13 away from the rocking frame 141A and are rotatablyfolded away from each other to stand on the ground. For retaining theextension leg 14A at a rocking position, the supporting stands 1431A arerotatably folded to overlap with the rocking frame 141A, wherein theswinging stands 1432A are outwardly extended from the two corner frames142A for limiting a rocking motion of the rocking frame 141A.

Furthermore, the supporting stand 1431A and the swinging stand 1432A areintegrally formed in a one-piece member and are rotatably coupled at thecorner frames 142A respectively. As shown in FIG. 12 , when the swingingstand 1432A is rotated to extend to the direction of the supporting leg13, the rocking frame 141A is supported on the ground. Via the curvatureof the rocking frame 141A, the extension legs 14 can be rocked at asideward rocking motion. Therefore, when the mattress 50A is placed inthe container body 30, the container body 30 serves as a baby crib orbaby cradle for a baby resting therein.

As shown in FIG. 13 , when the supporting stands 1431A are rotatablyextended to the direction of the supporting leg 13, the supportingstands 1431A are supported on the ground, such that the rocking frame141A is raised above the ground. Then, the extension leg 14A is stablysupported on the ground with four ground points. Therefore, when themattress 50A is placed on the container body 30A, the container body 30Aserves as a infant bed for a baby, and the foldable supporting frame 10serves as a rocking bed for the baby.

It is worth mentioning that the operation of the extension legs 14A willnot affect the unfolding and folding operations of the foldablesupporting frame 10. The mattress 50A further comprises with a mattresshandle 51A, wherein the mattress handle 51A is connected to theoperation switch 20 to be pulled up for actuating the folding operationof the operation switch 20.

According to the preferred embodiment, the present invention furtherprovides a folding method for the foldable container, which comprisesthe steps of:
